ABSTRACT:
A device which positively dispenses small, accurately measured, amounts of a flowable material, such as a resin, epoxy, etc. A pair of reciprocal pistons are movably mounted, each in a respective fluid pressure chamber, formed in a main body of a housing. One of the pistons moves a material dispense rod within a first section of a bore formed in a tubular portion of the housing. The second piston moves a sleeve which is telescopically mounted on the tubular housing between a material load position wherein flowable material is admitted into the first bore section, and a material discharge position wherein the first bore section is in communication with the second bore section. The dispense rod is moved into the first bore section to positively displace a predetermined amount of material from the device by movement of this same amount of material from the first bore section into the second bore section through a communication channel formed in the sleeve, thereby dispensing the same amount of material from a material outlet opening of the second bore section with each stroke of the dispense rod.
